Maxi Mounds (born October 25[1], 1964 in Rockville Centre, New York) is an Americannude model, stripper and porn star from Long Island, New York. Mounds is known for her extremely large breast implants. Mounds' implants are polypropylene string breast implants, which irritate the breast tissue, causing them to grow continuously as they fill with fluid. Mounds' breasts each weigh twenty pounds. She is tall at over 6 ft 0 in (1.83 m) in height.

Mounds has appeared in several softcore and hardcore porn videos and pictorials with Kayla Kleevage. According to her site, Maxi is working on several hardcore videos, which she rarely does, and these videos are some of the most anticipated videos on her site. She has done hardcore before, but this will be the first time with her largest breast implants.

Maxi Mounds holds the Guinness World Record for the "World's Largest Augmented Breasts." She approached Guinness in August of 2003, but the category did not yet exist.
